CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of International Application No. PCT/CN2014/088031, titled “APPARATUS FOR MANUFACTURING LIQUID STORAGE COTTON”, filed on Sep. 30, 2014, the entire disclose of which is incorporated herein by this reference.

TECHNICAL FIELD

The present application relates to the field of manufacturing electronic cigarette parts, and in particular to an apparatus for manufacturing liquid storage cotton.

BACKGROUND

An electronic cigarette includes a liquid storage assembly for storing cigarette liquid and an atomizing assembly for atomizing cigarette liquid in structure. Specifically, the atomizing assembly further includes an electric heating wire assembly for atomizing cigarette liquid. When the electronic cigarette operates, cigarette liquid flows into an atomizing chamber of the atomizing assembly from the liquid storage assembly, and the electric heating wire is powered by a battery rod to generate heat so as to atomize the cigarette liquid into smoke. In order to improve the efficiency of atomization of the electric heating wire, cigarette liquid is generally required to be stored around the electric heating wire uniformly, and in an existing electronic cigarette, the cotton used as a part by which cigarette liquid is stored around the electric heating wire uniformly is of columnar.

In conventional art, an apparatus for manufacturing the columnar cotton includes a melt-blown machine and a receiving device. As shown in FIG. 1, a base 101 is provided on the receiving device, and a first fixing seat 102, a second fixing seat 103, a first electrical motor 104, a second motor 105 and a rolling device 106 are provided at two ends of the base 101. A threaded guiding rod 107 is in an interference fit with the first fixing seat 102 and the second fixing seat 103, and a roller 108 is further provided on the second fixing seat 103. Both of the first electrical machine 104 and the second electrical machine 105 are connected to the threaded guiding rod 107 on the first fixing seat 103 through conveyor belts, and the melt-blown machine is located at a side of the threaded guiding rod 107 between the first fixing seat 102 and the second fixing seat 103. When the apparatus operates, the melt-blown machine blows cotton onto the threaded guiding rod 107. The threaded guiding rod 107 can be rotated by the first electrical machine 104, and the threaded guiding rod 107 can be rotated and moved by the second electrical machine 105, which may lead a different rotation speed with that rotated by the first electrical machine 104, such that the columnar cotton on the threaded guiding rod 107 is rotated and moved to another side of the second fixing seat 103 by the rolling device 106 on the second fixing seat 103. This process repeats and many pieces of columnar cotton are manufactured.

As the processing for electronic cigarette is getting fine, the diameter of the columnar cotton of the electronic cigarette is required to be small. In conventional art, however, when the columnar cotton to be manufactured is relatively small, the threaded guiding rod is required to have a very small diameter. If the diameter of the threaded guiding rod is too small, the frictional force between the threaded guiding rod and the cotton affixed on the threaded guiding rod is relatively small. Thus, when the columnar cotton is delivered outward by the threaded guiding rod through the second fixing seat, the columnar cotton may be stayed inbetween the first fixing seat and the second fixing seat when being blocked due to the relatively small frictional force between the columnar cotton and the threaded guiding rod. Thus the columnar cotton is unable to be delivered outward. Moreover, the columnar cotton manufactured by the threaded guiding rod forms a groove with an internal thread pattern due to the action of threads. Thus, the amount of cigarette can be stored is limited, and the flow of smoke is also blocked.

DETAILED DESCRIPTION

An apparatus for manufacturing liquid storage cotton is provided according to the present application. The specific structure of the apparatus for manufacturing liquid storage cotton according to the present application will be described in detail below in conjunction with FIG. 2.

In the present embodiment, the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device 201 and a melt-blown cotton receiving device         202 for receiving melted threads blown from the melt-blown         device to manufacture columnar liquid storage cotton.

The melt-blown cotton receiving device 202 is provided with a melted thread receiving rod 203 for attaching melted threads to form the columnar cotton and a first power device 204 for rotating the melted thread receiving rod.

The power device may be an electrical motor.

The melted thread receiving rod 203 is provided with a connecting section and a receiving section. The connecting section is connected with the first power device 204. The receiving section is configured to receive melted threads.

The melt-blown device is located at a side of the receiving section and blows melted threads to the receiving section continuously. The receiving section is rotated by the first power device to form the columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly 205, which is configured to detach the columnar cotton from the melted thread receiving rod 203 when the melted thread receiving rod 203 is rotated by the first power device 204 to form the columnar cotton.

The detaching assembly 205 includes a threaded sleeve 206 provided with inner threads, and the melted thread receiving rod 203 is arranged in a direct line with the threaded sleeve 206.

When columnar cotton is formed on the melted thread receiving rod 203, the inner threads of the threaded sleeve 206 closely fit the columnar cotton and allow the columnar cotton to be detached from the melted thread receiving rod 203.

When the inner threads of the threaded sleeve 206 closely fit the columnar cotton, the frictional force between the threaded sleeve and the columnar cotton is larger than the frictional force between the columnar cotton and the melted thread receiving rod. Therefore, the columnar cotton can be detached from the melted thread receiving rod and moved as the melted thread receiving rod rotates.

In the present embodiment, the threaded sleeve are provided with the inner threads to fit the columnar cotton, in this way, the diameter of the threaded sleeve is larger than the diameter of the melted thread receiving rod, thus the area of the inner threads of the threaded sleeve contacting with the columnar cotton is increased, thereby the frictional force is increased and transmission efficiency is improved.

In the embodiment described above, the melted thread receiving rod is rotated by the first power device, allowing a frictional force to be generated between the columnar cotton on the melted thread receiving rod and an inner side of the threaded sleeve and further allowing the columnar cotton to be detached from the melted thread receiving rod. In practical use, the detaching assembly further includes a second power device which is configured to rotate the threaded sleeve so as to detach the columnar cotton from the melted thread receiving rod. The second power device of the detaching assembly will be described below in conjunction with

FIG. 3. Another embodiment of the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device 201 and a melt-blown cotton receiving device         202 configured to receive melted threads blown from the         melt-blown device to manufacture columnar liquid storage cotton.

The melt-blown cotton receiving device 202 is provided with a melted thread receiving rod 203 configured to attach melted threads to form columnar cotton and a first power device 204 configured to rotate the melted thread receiving rod.

The power device may be an electrical motor.

The melted thread receiving rod 203 is provided with a connecting section and a receiving section. The connecting section is connected with the first power device 204, and the receiving section is configured to receive melted threads.

The melt-blown device is located at a side of the receiving section and blows melted threads to the receiving section continuously. The receiving section is rotated by the first power device to form the columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly 205, which is configured to detach columnar cotton from the melted thread receiving rod 203 when the melted thread receiving rod 203 is rotated by the first power device 204 to form the columnar cotton.

The detaching assembly 205 includes a threaded sleeve 206 provided with inner threads. The melted thread receiving rod 203 is arranged in a direct line with the threaded sleeve 206.

When the columnar cotton is formed on the melted thread receiving rod 203, the inner threads of the threaded sleeve 206 closely fit the columnar cotton and allow the columnar cotton to be detached from the melted thread receiving rod 203.

When the inner threads of the threaded sleeve 206 closely fit the columnar cotton, the frictional force between the threaded sleeve and the columnar cotton is larger than the frictional force between the columnar cotton and the melted thread receiving rod, therefore, the columnar cotton is detached from the melted thread receiving rod and moved as the melted thread receiving rod rotates.

The detaching assembly further includes a second power device 301.

The second power device 301 is configured to rotate the threaded sleeve 206 in direction opposite to the rotating direction of the melted thread receiving rod 203, thus when the melted thread receiving rod 203 is rotated to form the columnar cotton thereon, the columnar cotton is detached from the melted thread receiving rod by the threaded sleeve.

Since the frictional force between the columnar cotton and the threaded sleeve is larger than the frictional force between the columnar cotton and the melted thread receiving rod, the columnar cotton can definitely be detached from the melted thread receiving rod when the threaded sleeve and the melted thread receiving rod are rotated in opposite directions.

Correspondingly, the second power device 301 is configured to rotate the threaded sleeve 206 in a same direction with the rotating direction of the melted thread receiving rod 203.

A rotation speed of the threaded sleeve 206 driven by the second power device 301 is higher than a rotation speed of the melted thread receiving rod 203 driven by the first power device 204, thus when the columnar cotton is formed on the rotating melted thread receiving rod 203, the columnar cotton is detached from the melted thread receiving rod 203 by the threaded sleeve 206.

Since the frictional force between the columnar cotton and the threaded sleeve is larger than the frictional force between the columnar cotton and the melted thread receiving rod, the columnar cotton can definitely be detached from the melted thread receiving rod as there is a difference between rotation speeds of the threaded sleeve and the melted thread receiving rod.

In the present embodiment, the threaded sleeve is rotated by the second power device and the melted thread receiving rod is rotated by the first power device. Since the rotation speeds are different or opposite, the columnar cotton can be detached from the melted thread receiving rod. Because different electronic cigarettes requires different the columnar cotton, the threaded sleeve and the melted thread receiving rod are provided with a power device respectively so that factors such as the rotation speed of the melted thread receiving rod can be controlled in the manufacturing process for convenience, and individual parts can be finely adjusted in the manufacturing process, improving manufacturing efficiency.

In the embodiment described above, the inner threads of the threaded sleeve closely fit the columnar cotton, such that the columnar cotton is detached from the melted thread receiving rod. In the practical use, when the apparatus begins to operate, placing a first section of columnar cotton in the threaded sleeve is achieved by arranging a moving assembly. The moving assembly will be described specifically below in conjunction with FIG. 4. In the embodiment of the present application, another embodiment of the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device and a melt-blown cotton receiving device         configured to receive melted threads blown from the melt-blown         device to manufacture columnar liquid storage cotton.

The melt-blown cotton receiving device is provided with a melted thread receiving rod configured to attach melted threads for forming columnar cotton and a first power device configured to rotate the melted thread receiving rod.

The power device may be an electrical motor.

The melted thread receiving rod is provided with a connecting section and a receiving section. The connecting section is connected with the first power device, and the receiving section is configured to receive melted threads.

The melt-blown device is located at a side of the receiving section and blows melted threads to the receiving section continuously. The first power device rotates the receiving section to form the columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly, which is configured to detach columnar cotton from the melted thread receiving rod when the melted thread receiving rod is rotated by the first power device to form the columnar cotton.

The detaching assembly includes a threaded sleeve provided with inner threads. The melted thread receiving rod is arranged in a direct line with the threaded sleeve.

When the columnar cotton is formed on the rotating melted thread receiving rod, the inner threads of the threaded sleeve closely fit the columnar cotton and allow the columnar cotton to be detached from the melted thread receiving rod.

When the inner threads of the threaded sleeve closely fit the columnar cotton, the frictional force between the threaded sleeve and the columnar cotton is larger than the frictional force between the columnar cotton and the melted thread receiving rod, therefore, the columnar cotton is detached from the melted thread receiving rod and moved as the melted thread receiving rod rotates.

The detaching assembly further includes a second power device.

The second power device is configured to rotate the threaded sleeve in a direction opposite to the melted thread receiving rod, thus when the columnar cotton is formed the rotating melted thread receiving rod, the columnar cotton is detached from the melted thread receiving rod by the threaded sleeve.

Since the frictional force between the columnar cotton and the threaded sleeve is larger than the frictional force between the columnar cotton and the melted thread receiving rod, the columnar cotton can definitely be detached from the melted thread receiving rod as the threaded sleeve is rotated in a direction opposite to the rotating direction of the melted thread receiving rod.

Correspondingly, the second power device is configured to rotate the threaded sleeve in a same direction with the rotating direction of the melted thread receiving rod.

A rotation speed of the threaded sleeve driven by the second power device is higher than a rotation speed of the melted thread receiving rod driven by the first power device, thus when the columnar cotton is formed on the rotating melted thread receiving rod, the columnar cotton is detached from the melted thread receiving rod by the threaded sleeve.

Since the frictional force between the columnar cotton and the threaded sleeve is larger than the frictional force between the columnar cotton and the melted thread receiving rod, the columnar cotton can definitely be detached from the melted thread receiving rod as there is a difference between rotation speeds of the threaded sleeve and the melted thread receiving rod.

The apparatus for manufacturing liquid storage cotton is further provided with a baseplate 401, which is configured to fix the melt-blown device, the melt-blown cotton receiving device and the detaching assembly.

The apparatus for manufacturing liquid storage cotton further includes a moving assembly which is configured to move the melted thread receiving rod and the first power device when the columnar cotton melted threads is formed on the melted thread receiving rod.

Preferably, the moving assembly includes: a detector 402, a moving groove 403, a moving plate 404 located in the moving groove 403, and a power assembly 405.

The detector 402 is configured to detect whether the columnar cotton on the melted thread receiving rod has been formed before the melted thread receiving rod and the first power device are moved.

Both of the melted thread receiving rod and the first power device are located on the moving plate 404.

An end of the power assembly 405 is connected to the moving plate 404, and the other end of the power assembly 405 is fixed on the baseplate 401.

When the detector 402 detects that columnar cotton on the melted thread receiving rod has been formed, the power assembly 405 moves the moving plate 404 such that the melted thread receiving rod is embedded into the threaded sleeve by the moving groove 403.

Preferably, the power assembly 405 includes an air cylinder 406 and a connecting rod 407;

-   -   an end of the connecting rod 407 is retractably connected with         the air cylinder 406, and the other end of the connecting rod         407 is connected to the moving plate 404;     -   the air cylinder 406 is fixed on the baseplate 401.

In the present embodiment, when the apparatus begins to operate, the detector detects whether the columnar cotton has been formed by melted threads on the melted thread receiving rod, then the moving assembly is controlled such that the melted thread receiving rod is embedded into the threaded sleeve, allowing the columnar cotton to closely fit with the threaded sleeve. In this way, a full automatic production of the apparatus is realized and the usability of the apparatus is improved.

In the embodiment described above, the melted thread receiving rod is moved by the moving assembly so as to be embedded into the threaded sleeve. In the practical use, the columnar cotton on the melted thread receiving rod can be directly moved into the threaded sleeve by the moving assembly. Another device of the moving assembly will be described specifically below in conjunction with FIG. 5. In the embodiment of the present application, another embodiment of the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device and a melt-blown cotton receiving device         configured to receive melted threads blown from the melt-blown         device to manufacture a columnar liquid storage cotton.

The melt-blown cotton receiving device is provided with a melted thread receiving rod configured to attach melted threads to form columnar cotton and a first power device configured to rotate the melted thread receiving rod.

The power device may be an electrical motor.

-   -   the melted thread receiving rod is provided with a connecting         section and a receiving section, and the connecting section is         connected with the first power device, and the receiving section         is configured to receive melted threads.     -   the melt-blown device is located at a side of the receiving         section and blows melted threads to the receiving section         continuously, and the first power device rotates the receiving         section to form columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly, which is configured to detach columnar cotton from the melted thread receiving rod as the first power device rotates the melted thread receiving rod to form the columnar cotton;

-   -   the detaching assembly includes a threaded sleeve provided with         inner threads, and the melted thread receiving rod is arranged         in a direct line with the threaded sleeve.     -   when the columnar cotton is formed on the melted thread         receiving rod, the inner threads of the threaded sleeve closely         fit the columnar cotton and allow the columnar cotton to be         detached from the melted thread receiving rod.

When the inner threads of the threaded sleeve closely fit the columnar cotton, the frictional force between the threaded sleeve and the columnar cotton is larger than the frictional force between the columnar cotton and the melted thread receiving rod, therefore, the columnar cotton is detached from the melted thread receiving rod and moved as the melted thread receiving rod rotates.

The detaching assembly further includes a second power device.

-   -   the second power device is configured to rotate the threaded         sleeve in a direction opposite to the rotating direction of the         melted thread receiving rod, such that when the columnar cotton         is formed on the melted thread receiving rod, the columnar         cotton is detached from the melted thread receiving rod by the         threaded sleeve.     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod when the threaded sleeve and the melted         thread receiving rod are rotated in opposite directions.

Correspondingly, the second power device is configured to rotate the threaded sleeve in a same direction with the rotating direction of the melted thread receiving rod 203;

-   -   a rotation speed of the threaded sleeve driven by the second         power device is higher than a rotation speed of the melted         thread receiving rod driven by the first power device, such that         when the columnar cotton is formed on the melted thread         receiving rod, the columnar cotton is detached from the melted         thread receiving rod by the threaded sleeve;     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod as there is a difference between rotation         speeds of the threaded sleeve and the melted thread receiving         rod.

The apparatus for manufacturing liquid storage cotton is further provided with a baseplate 501 which is configured to fix the melt-blown device, the melt-blown cotton receiving device and the detaching assembly;

-   -   the apparatus for manufacturing liquid storage cotton further         includes a moving assembly which is configured to move the         columnar cotton on the melted thread receiving rod into the         threaded sleeve before the columnar cotton closely fits the         inner threads of the threaded sleeve.

Preferably, the moving assembly includes a moving track 502 provided on the baseplate 501 and a moving arm located on the moving track 502.

-   -   the moving arm includes: a first air cylinder 504, a second air         cylinder 505, a third air cylinder 506 and a clamping finger         507;     -   the first air cylinder 504 is configured to allow the clamping         finger 507 to extend to the columnar cotton before the columnar         cotton on the melted thread receiving rod closely fits the inner         threads of the threaded sleeve 206;     -   the third air cylinder 506 is configured to allow the clamping         finger 507 to clamp the columnar cotton when the clamping finger         507 is moved to the columnar cotton;     -   the second air cylinder 505 is configured to allow the clamping         finger 507 to move towards the threaded sleeve when the clamping         finger 507 clamps the columnar cotton, such that the columnar         cotton closely fits the inner threads of the threaded sleeve         206.     -   when the clamping finger 507 moves the columnar cotton to         closely fit the inner threads of the threaded sleeve, the third         air cylinder 506 allows the clamping finger 507 to release the         columnar cotton.     -   when the clamping finger 507 releases the columnar cotton, the         first air cylinder 504 allows the clamping finger 507 to retract         away from the columnar cotton.     -   when the clamping finger 507 retracts away from the columnar         cotton, the second air cylinder 505 allows the clamping finger         507 to move away from the threaded sleeve.

Preferably, the moving arm is further provided with a sliding track 508, a connecting block 509 and a moving base 510;

-   -   the moving base 510 is located in the moving track 502;     -   the connecting block 509 is located in the sliding track 508 for         connecting the clamping finger 507 and the moving base 510.

In the present embodiment, when the apparatus begins to operate, the clamping finger clamps the columnar cotton formed on the melted thread receiving rod and further embed it into the threaded sleeve by three air cylinders, at this time, the columnar cotton begins to be detached from the melted thread receiving rod, such that subsequent columnar cotton is driven by the threaded sleeve effectively to be detached from the melted thread receiving rod and moved.

In the embodiment described above, a relatively large frictional force is generated between the threaded sleeve and the columnar cotton, such that the columnar cotton is detached from the melted thread receiving rod. In the practical use, after the columnar cotton is detached, the columnar cotton is required to be rolled to have a smooth outer circumferential surface and become the required part. A rolling component configured to roll the columnar cotton detached from the melted thread receiving rod will be described specifically below in conjunction with FIG. 6. In the embodiments of the present application, another embodiment of the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device 201 and a melt-blown cotton receiving device         202 configured to receive melted threads blown from the         melt-blown device to manufacture a columnar liquid storage         cotton.

The melt-blown cotton receiving device 202 is provided with a melted thread receiving rod 203 configured to attach melted threads to form columnar cotton, and a first power device 204 configured to rotate the melted thread receiving rod;

-   -   the power device may be an electrical machine.

The melted thread receiving rod 203 is provided with a connecting section and a receiving section, and the connecting section is connected with the first power device 204; and the receiving section is configured to receive melted threads.

-   -   the melt-blown device is located at a side of the receiving         section and blows melted threads to the receiving section         continuously; and the first power device rotates the receiving         section to form columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly 205, which is configured to detach columnar cotton from the melted thread receiving rod 203 as the first power device 204 rotates the melted thread receiving rod 203 to form the columnar cotton;

-   -   the detaching assembly 205 includes a threaded sleeve 206         provided with inner threads, and the melted thread receiving rod         203 is arranged in a direct line with the threaded sleeve 206;     -   when the columnar cotton is formed on the melted thread         receiving rod 203, the inner threads of the threaded sleeve 206         closely fit the columnar cotton and allow the columnar cotton to         be detached from the melted thread receiving rod 203;     -   when the inner threads of the threaded sleeve 206 closely fit         the columnar cotton, the frictional force between the threaded         sleeve and the columnar cotton is larger than the frictional         force between the columnar cotton and the melted thread         receiving rod, therefore, the columnar cotton is detached from         the melted thread receiving rod and moved as the melted thread         receiving rod rotates.

The detaching assembly further includes a second power device 301;

-   -   the second power device 301 is configured to rotate the threaded         sleeve 206 in a direction opposite to the rotating direction of         the melted thread receiving rod 203, such that when the columnar         cotton is formed on the rotating melted thread receiving rod         203, the columnar cotton is detached from the melted thread         receiving rod by the threaded sleeve;     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod when the threaded sleeve and the melted         thread receiving rod are rotated in opposite directions.

Correspondingly, the second power device 301 is configured to rotate the threaded sleeve 206 in a same direction with the rotating direction of the melted thread receiving rod 203;

-   -   a rotation speed of the threaded sleeve 206 driven by the second         power device 301 is higher than a rotation speed of the melted         thread receiving rod 203 driven by the first power device 204,         such that when the columnar cotton is formed on the rotating         melted thread receiving rod 203, the columnar cotton is detached         from the melted thread receiving rod 203 by the threaded sleeve         206.     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can indefinitely be detached from the melted         thread receiving rod as there is a difference between rotation         speeds of the threaded sleeve and the melted thread receiving         rod.

The apparatus for manufacturing liquid storage cotton further includes a rolling component;

-   -   the rolling component is configured to roll the columnar cotton         detached from the melted thread receiving rod.

Preferably, the rolling component includes: multiple rollers 601, and a roller supporting block 602 for supporting the rollers;

-   -   when the columnar cotton already moved by the threaded sleeve         206 moves into the rolling component, the rollers 601 closely         fit the columnar cotton to move synchronously.

Preferably, the apparatus for manufacturing liquid storage cotton further includes a receiving groove 603, and a fixing block 604 for fixing the receiving groove.

-   -   the receiving groove 603 is configured to receive the columnar         cotton detached from the melted thread receiving rod 203;     -   the receiving groove 603 is configured to deliver the columnar         cotton to the rolling component.

In the present embodiment, the outer circumferential surface is rolled uniformly by the rollers through the synchronous rotation of the multiple rollers and the columnar cotton, thus the outer circumferential surface of the columnar cotton rolled is smooth.

In the embodiment described above, the first power device rotates the melted thread receiving rod and the second power device rotates the threaded sleeve. The threaded sleeve allows the columnar cotton to be detached from the melted thread receiving rod due to different rotation speeds or different rotating directions. In the practical use, a first connecting component configured to connect the first power device and the melted thread receiving rod and a second connecting component configured to connect the second power device and the threaded sleeve are provided. The connecting components will be described specifically below in conjunction with FIG. 7, in the embodiments of the present application, another embodiment of the apparatus for manufacturing liquid storage cotton includes:

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly, which is configured to detach columnar cotton from the melted thread receiving rod 203 as the melted thread receiving rod 203 is rotated by the first power device 204 to form the columnar cotton.

-   -   the detaching assembly includes a threaded sleeve 206 provided         with inner threads, and the melted thread receiving rod 203 is         arranged in a direct line with the threaded sleeve 206;     -   when the columnar cotton is formed on the melted thread         receiving rod 203, the inner threads of the threaded sleeve 206         closely fit the columnar cotton and allow the columnar cotton to         be detached from the melted thread receiving rod 203;     -   when the inner threads of the threaded sleeve closely fit the         columnar cotton, the frictional force between the threaded         sleeve and the columnar cotton is larger than the frictional         force between the columnar cotton and the melted thread         receiving rod, therefore, the columnar cotton is detached from         the melted thread receiving rod and moved as the melted thread         receiving rod rotates.

The detaching assembly further includes a second power device 301;

-   -   the second power device 301 is configured to rotate the threaded         sleeve 206 in a direction opposite to the rotating direction of         the melted thread receiving rod 203, such that when the columnar         cotton is formed on the rotating melted thread receiving rod         203, the columnar cotton is detached from the melted thread         receiving rod by the threaded sleeve.     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod as the threaded sleeve and the melted         thread receiving rod are rotated in opposite directions,.

Correspondingly, the second power device 301 is configured to rotate the threaded sleeve 206 in a same direction with the rotating direction of the melted thread receiving rod 203;

-   -   a rotation speed of the threaded sleeve 206 driven by the second         power device 301 is higher than a rotation speed of the melted         thread receiving rod 203 driven by the first power device 204,         thus when the columnar cotton is formed on the rotating melted         thread receiving rod 203, the columnar cotton is detached from         the melted thread receiving rod 203 by the threaded sleeve 206;     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod as there is a difference between rotation         speeds of the threaded sleeve and the melted thread receiving         rod.

In the embodiment described above, columnar cotton is formed by the melted threads on the rotating melted thread receiving rod. In the practical use, a protrusion may be provided on the outer circumferential surface of the melted thread receiving rod for facilitating attaching melted threads. The apparatus for manufacturing liquid storage cotton may be further provided with a cooling device for cooling the melted thread receiving rod. The melted thread receiving rod and the cooling device will be described specifically below with reference to FIG. 6, in the embodiment of the present application, another embodiment of the apparatus for manufacturing liquid storage cotton includes:

-   -   a melt-blown device 201 and a melt-blown cotton receiving device         202 configured to receive melted threads blown from the         melt-blown device to manufacture a columnar liquid storage         cotton.

-   -   the power device may be an electrical motor.

The melted thread receiving rod 203 is provided with a connecting section and a receiving section, and the connecting section is connected with the first power device 204, and the receiving section is configured to receive melted threads;

-   -   the melt-blown device is located at a side of the receiving         section and blows melted threads to the receiving section         continuously, and the receiving section is rotated by the first         power device to form columnar cotton.

The apparatus for manufacturing liquid storage cotton further includes a detaching assembly 205, which is configured to detach columnar cotton from the melted thread receiving rod 203 as the melted thread receiving rod 203 is rotated by the first power device 204 to form the columnar cotton;

-   -   the detaching assembly 205 includes a threaded sleeve 206         provided with inner threads, and the melted thread receiving rod         203 is arranged in a direct line with the threaded sleeve 206;     -   when the columnar cotton is formed on the melted thread         receiving rod 203, the inner threads of the threaded sleeve 206         closely fit the columnar cotton and allow the columnar cotton to         be detached from the melted thread receiving rod 203.     -   when the inner threads of the threaded sleeve 206 closely fit         the columnar cotton, the frictional force between the threaded         sleeve and the columnar cotton is larger than the frictional         force between the columnar cotton and the melted thread         receiving rod, therefore, the columnar cotton is detached from         the melted thread receiving rod and moved as the melted thread         receiving rod rotates.

The detaching assembly further includes a second power device 301;

-   -   the second power device 301 is configured to rotate the threaded         sleeve 206 in a direction opposite to the rotating direction of         the melted thread receiving rod 203, thus when the columnar         cotton is formed on the rotating melted thread receiving rod         203, the columnar cotton is detached from the melted thread         receiving rod by the threaded sleeve;     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod as the threaded sleeve and the melted         thread receiving rod are rotated in opposite directions.

Correspondingly, the second power device 301 is configured to rotate the threaded sleeve 206 in a direction same with the rotating direction of the melted thread receiving rod 203;

-   -   a rotation speed of the threaded sleeve 206 driven by the second         power device 301 is higher than a rotation speed of the melted         thread receiving rod 203 driven by the first power device 204,         thus when the columnar cotton is formed on the rotating melted         thread receiving rod 203, the columnar cotton is detached from         the melted thread receiving rod 203 by the threaded sleeve 206;     -   since the frictional force between the columnar cotton and the         threaded sleeve is larger than the frictional force between the         columnar cotton and the melted thread receiving rod, the         columnar cotton can definitely be detached from the melted         thread receiving rod as there is a difference between rotation         speeds of the threaded sleeve and the melted thread receiving         rod;

An outer circumferential surface of the receiving section is not provided with an external thread;

-   -   in the conventional art, the columnar cotton is detached and         moved by providing an external thread on the melted thread         receiving rod, however, in the present application, instead of         an external thread, the melted thread receiving rod is provided         with a threaded sleeve to detach and move the columnar cotton,         therefore, the present application is essentially different from         the conventional art in technical feature.

Each of cross sections of the receiving section at different positions along an axial direction thereof is of a convex polygonal shape.

Reference is made to FIG. 6. Preferably, the apparatus for manufacturing liquid storage cotton further includes a cooling device 801, and the melted thread receiving rod 203 is a metal rod, and a cooling channel is provided in the metal rod in an axial direction of the metal rod, and the melted thread receiving rod 203 is cooled by the cooling device 801 via the cooling channel;

-   -   since the melted thread receiving rod continuously receives melt         blow from the melt-blown machine, the temperature can be         increased continuously, which is not easy to form and cool the         columnar cotton, however, cooling the melted thread receiving         rod by the cooling device may facilitate the formation of the         columnar cotton, and providing a cooling channel on in the         melted thread receiving rod also prevents liquid in the cooling         device from contaminating the columnar cotton on the melted         thread receiving rod.

Preferably, the threaded sleeve is a half-threaded sleeve.

-   -   since the threaded sleeve acts on the columnar cotton, a thread         pattern is formed on the outer circumferential surface of the         columnar cotton, and the outer circumferential surface of the         columnar cotton is not smooth. In order to reduce the thread         pattern of the columnar cotton, the threaded sleeve is         configured into a half-threaded sleeve. It should be noted that         as long as the frictional force between the threaded sleeve and         the columnar cotton is large enough, the inner threads of the         threaded sleeve can be set in any pattern.

In the present embodiment, the melted thread receiving rod is not provided with an external thread, thus there is no thread pattern on the inner side of the columnar cotton detached, which prevents the columnar cotton from blocking the flow of smoke and limiting the amount of cigarette liquid when being used in an electronic cigarette device. The apparatus for manufacturing liquid storage cotton is further provided with a cooling device, which is configured to cool the melted thread receiving rod, thus the columnar cotton is easier to be formed and cooled, improving the quality of production.

The above embodiments are only used for illustrating the technical solution of the present application, not for limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood for those skilled in the art that modifications can also be made to the technical solution set out in the foregoing embodiments, or equivalents can be made to part of the technical features; and those modifications and equivalents do not make the nature of the corresponding technical solution depart form the spirit and scope of the technical solutions of the embodiments of the present application.
